AIR-WASHER HUMIDIFIER non irrrniiiicziis.

lApplication led June 20, 1921. Serial No.V 478,847.

Be it known that I, JOHN citizen of the United States, `residing at Chi- .a specification.

. nacesto which Y adapted.

cago, in the county of CookV and 'State of Illinois, have invented certain new and useiiers lfor Furnaces, of which the following-is This invention. relates to means for suitably disposing. a water supplyto wash and saturate the air which is distributedv by hot 'air furnaces, and whileit. is particularly designed for that class of furnaces which are known in the trade; asp1peless furnaces it may beusedfwith Vany other kind of fur-Iy it -is or may be conveniently lThe object of the invention is .to providey means of simple character for holding` a supply of water in sufficient quantity and in an advantageous position to thoroughly wash and saturate the air during its passage through' the furnace so that it will be delivered in a clean and properly saturated condition and thus avoid the dust and dryness common to hot air furnaces.

A further object of the invention is to provide a plurality of communicating pans for holding the water supply, these pans being of a size Vand shapev which will permit them to be easily removed from the furnace for cleaning, and as easily replaced.

And further objects vare to provide simple Y means for filling the pans and means for indicating the depth'of water in the pans.

In the accompanying drawing illustrating a selected embodiment of the inventioni A .v A

Fig. 1 is a perspective view of a pipeless furnace, partly broken away,and in section,

' showing my invention embodied therein;

Fig. 2 is a rear perspective view ofthe furnace with the Vjackets or shells removed; Fig. 3 is a detail sectional view pn the line 3-3 of Fig. 1 showing the Vindicating means. Y

Referring to the drawing, the furnace 1s designated generally .4 and it comprises an outer jacket or lshell 5 supported on a base 6, and an inner'jacket 7 supported on arms or brackets 8, the two jackets being spaced Aapart to provide an air passage 9, and the arms 8 being located to support the inner jacket 7 at a distance above the base so that air passing down through the passagel vful Improvements Ain Air-I/Vasher I-Iumidi-V supply of water inthe bottom of the furnace" vto thoroughly wash and saturate the inflow- 9 may passirundevr the lower edgel'of theinnerjacket 7 andthence up betweeiisaidinner jacketqand the body ofthe furi'iace'in col ports 10, lOwvhich may be made of channel iron or Va Z-bar to which lthe ends of` .s the jackets arefsecured.L l. i .Y

I providea plurality of pans 11,-12,13', i ,Y

which are arranged in juXta-position within the outer jacket and. decrease in depthprogressively in the order named. y'Thepan 11 is provided at its'discharge end with a downwardly and outwardly inclined flange. 11 overlappingy they adjacent edge of the pan 12 andthe latter is similarly provided witha flange 12 which overlaps an adjacentedge vof the pan 13, so thatjwatermay over-flow from the pan 111 to the pan 12 and from the pan 12 to the panr13. A

pipe 14 is supported in one of the supports, as 10,.-and it is provided atgits outer end with an inlet 15 into which .the'water is poured to flow through the pipe 14 into the pan 11. The indicating means for determining thevlevel of the water in the pan 13 comprises a float 16 connectedvwith a lever 17 which is pivoted at 18- on the supportV 10, and one endy of this lever projects through an opening 19 in said support and is provided with a pointer 20 which indi-' cates the'level of the waterV in the pan 13 by its position 'relative to suitable marks on the support.V A. guard 21 carried by'a bracket 22 suitably secured tothe support 10 is provided with a flared lower end 21* to keep the float in properfoperative positlOIl'. l i 'f It will thus be seen that means I am able to maintain a suiiicient ing air in its' passage to the heating chamber 23 and before it is discharged from the furf 1 l nace. The water pans are located at the bottom of the passage 9I from one support bly-Avery` simple 1() to the other 10 so'thatvall of the air is f thoroughly cleaned and saturated. In' ac-,I`

tual practice it has been found that the pans will collect a considerable quantity of dirty in a comparatively short time and for this reason it is desirable to have'a plurality of pans which can be easily removed from the furnace and as easily rearranged in place in f proper relation to each other and so that ics l' one will over-flow into the other, this con-V struction being desirable in order that the installed, it can be made and installedat low cost and it enables an ample and sufficient supply of water to be maintained where it will not only wash and clean the air but also saturate it to a degree of humidity which isA most desirable in hot air heated homes.

I am aware that changes in the form and in the proportion and arrangement of parts may be made without departing from the spirit or sacrificing the advantages of my invention and reserve the right to make all such changes as fairly fall within the scope of the following claims:

claim: f

l. Ina hot air furnace, the combination of a base, a fire box supported thereon, an outer shell rising from the base, an inner jacket between the shell and the fire box and havingits bottom terminated above the base to provide a communication between the do-wn draft air space between the acket and the shell andthe up draft air space between theljacket and the iire box, a plurality of reins/4,639 Y Vwater in the pans.

2. lna hot air furnace, the combination of a base, a fire box supported thereon, an outer shell rising from the base, an inner .jacket between the shell and the lire box and having'v its bottom terminated above the base to provide a communication between the down draft air space between the jacket and the shell and the up draft air spaceV between the jacket and the fire box, a plural-v ity of removable open topped water pans supported on the base and extending around the lire box, successiveV pans having a detachable overflow connection consisting of a downwardly and outwardly inclined flange at the discharge end of one of the pans and overlapping the adjacent edge of the next successive pan, a water supply pipe extend-v ing inwardly through the outer shell and, communicating with oner of the terminal pans, a oat within the opposite terminal pan, and a waterlevel indicator associated with the iioat and extending ,outwardly through an opening in thev shell.
